• Strengths:
  • The student demonstrates a good understanding of backtracking and recursion.
  • The time and space complexity analyses are accurate.
  • The second implementation of combinationSum is clean and efficient.
• Areas for Improvement:
  • The first combinationSum implementation is overly complex. Simplifying it to match the second implementation would improve readability and maintainability.
  • The use of c in the first implementation is unnecessary and complicates the logic. Standard backtracking without this counter would be clearer.
  • The addOperators solution is well-done, but the student could consider adding comments to explain the tail approach more clearly for better readability.
